Yes.

And, yet, the CBP can cause you any number of headaches and subject you to intimidation and humiliation prior to your actually being waved through -- especially if they deem you "difficult".

Similar to lots of the other comments in this thread, I'm subjected to additional screenings every time I come back into the country. I'm a completely average middle-aged white guy and I have no idea why this happens. Is it because I'm anxious? I have a somewhat common name; perhaps they've confused me with someone else? Was it because I was at Schipol the same time as The Underwear Bomber or because I went to Turkey on vacation? I will (probably) never know why but it's so unpleasant that I've stopped leaving the country for fun (something I used to love) and has had a real, negative effect on my relationship with my spouse.
